This inventionrelates to a'power pressv with automatic feed,and means ifor ejecting the bricks froml the mold and lfor the discharge of the bricksj y The Whole manipulation of the productsk Whether they are beingintroduced into, or

removed from, the' mould, takes place out of reach of the movingl compression pistons, which precludes any possibility of accidents during the working. c

The brick Which is thus introduced into the mold is a castwhavingv va form Which closely resembles that of the rproduct after compression, and this castV beingfnecessarily constituted of 'plastic material, semi-hard or solid, of ordinary refractoryearth clay, having been'passe'd through a draw 'plate or 4other suitable apparatus.Y

rllhe main shaft driying;r the various parts,

is driven a motor either directly or through a reducing gearysuclias a Worm gear, gear ivheels, etc.. This main shaft car-V ries an eccentric with 4a travel, driving i. the compressionrod which v intervenes only j. in order to compress the brickfintroduced into `the mould by auxiliary parts.

V This arrangement which is rendered possibleby the inclusion -or' auxiliary parts for the introductionof the brick into the mould, enables the stress to be distributed over a maXimZumo-E time, so that' the Lpower 4retjuireijl to obtainthe necessary pressure, is considerablyreduced.

of a two-armed lever 0,' these two arins'each terminate in a. roller, and a'cam" placts/ alternately on each l of -the said rollers' in ordei-to transmit to the toothed quadrant m s its necessary rockingmovement. Y

The brick having` been' pushed into the4V mould, an adjustable shutter vg` yis brought The brick ,is Aplaced on the or during the'return movement of thel latter ends.v

behind the rod ot the plunger a'v in order to g maintain Athe latter stationary duringl the compression produced by the v second piston vZ which receives thel impact of the connecting rod lV, with which it is connected.

rEhis shutter Q is connected to a bell crank lever 's whichin its turn is connected by a rod t to a bifurcated lever it, the two branches of which, terminating in rollers like thelever 0, are alternately operated by the mechanical means causes theplungers z' and r to traverse a path` suiliciently long but .vithout having any important power to furnish, that which justifies their actuation by cams and levers, so tliat'plunger .e is controlled by a crank oi' eccentric on the shaft Z2 and furnishes the compression with a very small displacement or 'extent o'l movement ot'said plunger. rlhe member fafhas a flange n fixed thereto, and the segment c has a' downwardly projecting arm which is vprovided at its lower end with a iiork, the tingers w of which are arranged astride of the i'neiiibei` a and behind the tlange a. Hence the plunger z is permitted to.operate the plunger f1', to compress the brick, the com* pressing movements ot said pluugers being slight, without affecting the plunger 'i which will be held during such compression by the shutter gf The supplementary pressure due Yto the excess oil thickness of the brick, is absorbed by the resiliency of Belleville washers 'y or by some other 'spring mechanism. rShe thickness oi" the bricks can fbe regulated during'the working by means ot horseshoe shaped washers inserted betweenv theconfin presser plunger .e and the ejecting plunger i". The compressing plunger has a bore in which the ,steml ot' the ejecting plunger op crates, as shown in Figure l. Interchangeabler moulds make it possible to obtain bricks oi'f variable dimensionsgyit is only necessary to vary. the height of the table by .liding it on its supports.

The brick is carried away bythe table t `ttor it has been removed trom the mould. in additional df ving device is provided in case the brick sticks tothe ejecting plunger on account ot lhe state' of the clay or of the lubricant used. 'lhisdriviiig device is constitutedrby a pivoted auxiliary table which.

is raised after the brick has been eiected from the nioldgit pushes the brick parallel. to the 'tace adhering to the ejecting plunger, detachee it and carries it auf'ajv. 'lhe abut'- inernt 'i is ineffect stationary and independent or" the table. rlie workman placesk in the interior of its rack and against the same a cast lto be molded, as indicated in Fig. Ll. Assuming that the table has not terminated its movement of separation 'from the mold,

the cast moved by the; table remains stationary by virtue or' the racks of lan abut.-V ment. AfterY the table returns toward the mold, the cast is still in the vsame position and toward the end of the table movement arrives in a position bet'ore the mold whereupon the workman is enabled to place vdurl ing this time a new cast against the rack ot the abutment.

'lhe cliiet characteristic features ot' the invention are as 'follows 2'-,

l. The machine is power driven, with.

automatic feeding motions for' vu'nmoulding ments of great ,amplitude are brought aboutby parts driven independently ot' the compressing piston. d. rlhe thickness of the brickcan be regulated during the operation ot' the press.

5. The pistons are'arranged horizontally,

which is avery convenient method.

G. rlhe reciprocating motion of the table takes place with a pause at the end ot each angle of rotation. All the auxiliary movestroke, obtained by means ot avbevel quadrant provided withteeth only on a portion of the ,circumference and engaging alternately Vwith two bevel pinions.

With the said machine could be combined: a device'by means ot' which continuous working Vor working with an auto- Vmaticy stop after eachmoulding can be obtained Yat will.
